Columbidae is the pigeon family of birds of the order Gallinae. They are characterized by the hind toe being nearly on the same plane as the others. The bill is moderate and deflected at the tip, the upper mandible covered at the base with a soft membrane. The tarsi are devoid of spurs and the tail is comprised of twelve feathers. They have considerable powers of flight, and perch freely on trees and rocks. They feed principally on grain, seeds and the leaves of herbaceous plants. The young are fed on a milky fluid secreted in the crop of the older birds. Research Columbidae
The Dodo (Didus ineptus) was a huge, flightless bird of the pigeon order, Columbidae, formerly found in abundance only on the island of Mauritius. The Dodo had rudimentary wings, short, stout legs and a tail of soft plumage. The beak was strongly arched towards the end, and the upper mandible had a hooked point like that of a bird of prey. In 1644 when the island was first colonised by the Dutch the dodo was present in great numbers, but within forty years a combination of the loss of natural habitat to cyltivation and hunting for food led to the Dodo's extinction in the first and most famous ecological tragedy committed by Man.
In 2002 scientists at Oxford university, England extracted DNA from the only remaining Dodo tissue in existence and claimed to have discovered that the Dodo was a pigeon. However, this had already been known for at least 100 years, as evidenced by Lloyd'sEncyclopaediaDictionary, published in 1895 by Edward Lloyd Limited of London describes the dodo as 'A large bird, belonging to the order Columbidae, or Pigeons'.
